Analysis of movement quality in full-body physical activities

Full-body human movement is characterized by fine-grain expressive qualities that humans are easily capable of exhibiting and recognizing in others' movement. In sports (e.g., martial arts) and performing arts (e.g., dance), the same sequence of movements can be performed in a wide range of ways characterized by different qualities, often in terms of subtle (spatial and temporal) perturbations of the movement. Even a non-expert observer can distinguish between a top-level and average performance by a dancer or martial artist. The difference is not in the performed movements-the same in both cases-but in the \u201cquality\u201d of their performance. In this article, we present a computational framework aimed at an automated approximate measure of movement quality in full-body physical activities. Starting from motion capture data, the framework computes low-level (e.g., a limb velocity) and high-level (e.g., synchronization between different limbs) movement features. Then, this vector of features is integrated to compute a value aimed at providing a quantitative assessment of movement quality approximating the evaluation that an external expert observer would give of the same sequence of movements. Next, a system representing a concrete implementation of the framework is proposed. Karate is adopted as a testbed. We selected two different katas (i.e., detailed choreographies of movements in karate) characterized by different overall attitudes and expressions (aggressiveness, meditation), and we asked seven athletes, having various levels of experience and age, to perform them. Motion capture data were collected from the performances and were analyzed with the system. The results of the automated analysis were compared with the scores given by 14 karate experts who rated the same performances. Results show that the movement-quality scores computed by the system and the ratings given by the human observers are highly correlated (Pearson's correlations r = 0.84, p = 0.001 and r = 0.75, p = 0.005)

Intensification of social behavior in community development: An approach to applied social psychology

Purpose - This article aims to: First, identify social behavior in community development both as knowledge and action. Second, analyzing social behavior in community development through an applied social psychology approach.Method - research type used library research.Result - The results of the discussion show: First, today's social behavior in community development is facing various challenges along with the social dynamics themselves. In order to maintain and develop the existence of community development, it is necessary to involve other scientific disciplines. The involvement of other scientific disciplines, one of which is intended in an effort to intensify social behavior in the development of society itself. Second, the applied social psychology approach can be used in the realm of understanding social problems, identifying factors that influence social attitudes and behavior, interventions, designing social change, and evaluating activity programs.Implications - This study the impact on the development of applied social psychology approaches can be applied to the realm of understanding social problems, identifying factors that influence social attitudes and behavior, interventions, designing social change, and evaluating activity programs. In addition, applied social psychology can also be used as an approach in strengthening attitudes and behavior in intensifying community development.Originality - This research is strengthening intensification of social behavior in community development to applied social psychology.***Tujuan - Artikel ini bertujuan: Pertama, mengidentifikasi perilaku sosial dalam pengembangan masyarakat baik sebagai pengetahuan maupun tindakan. Kedua, menganalisis perilaku sosial dalam pengembangan masyarakat melalui pendekatan psikologi sosial terapan.Metode - jenis penelitian yang digunakan adalah penelitian kepustakaan.Hasil - Hasil pembahasan menunjukkan: Pertama, perilaku sosial masyarakat dewasa ini menghadapi berbagai tantangan seiring dengan dinamika sosial itu sendiri. Dalam rangka menjaga dan mengembangkan keberadaan pengembangan masyarakat, perlu melibatkan disiplin ilmu lain. Keterlibatan disiplin ilmu lain, salah satunya dimaksudkan dalam upaya mengintensifkan perilaku sosial dalam pembangunan masyarakat itu sendiri. Kedua, pendekatan psikologi sosial terapan dapat digunakan dalam ranah memahami masalah sosial, mengidentifikasi faktor-faktor yang mempengaruhi sikap dan perilaku sosial, intervensi, merancang perubahan sosial, dan mengevaluasi program kegiatan.Implikasi - Studi ini memiliki dampak terhadap pengembangan pendekatan psikologi sosial terapan dapat diterapkan pada ranah pemahaman masalah sosial, mengidentifikasi faktor-faktor yang mempengaruhi sikap dan perilaku sosial, intervensi, merancang perubahan sosial, dan mengevaluasi program kegiatan. Selain itu, psikologi sosial terapan juga dapat digunakan sebagai pendekatan dalam penguatan sikap dan perilaku dalam mengintensifkan pembangunan masyarakat.Orisinalitas - Penelitian ini memperkuat intensifikasi perilaku sosial dalam pengembangan masyarakat terhadap psikologi sosial terapan

Interpersonal sensorimotor communication shapes intrapersonal coordination in a musical ensemble

Social behaviors rely on the coordination of multiple effectors within one’s own body as well as between the interacting bodies. However, little is known about how coupling at the interpersonal level impacts coordination among body parts at the intrapersonal level, especially in ecological, complex, situations. Here, we perturbed interpersonal sensorimotor communication in violin players of an orchestra and investigated how this impacted musicians’ intrapersonal movements coordination. More precisely, first section violinists were asked to turn their back to the conductor and to face the second section of violinists, who still faced the conductor. Motion capture of head and bow kinematics showed that altering the usual interpersonal coupling scheme increased intrapersonal coordination. Our perturbation also induced smaller yet more complex head movements, which spanned multiple, faster timescales that closely matched the metrical levels of the musical score. Importantly, perturbation differentially increased intrapersonal coordination across these timescales. We interpret this behavioral shift as a sensorimotor strategy that exploits periodical movements to effectively tune sensory processing in time and allows coping with the disruption in the interpersonal coupling scheme. As such, head movements, which are usually deemed to fulfill communicative functions, may possibly be adapted to help regulate own performance in time

Holographic Leadership: Leading as a Way of Being

Holographic Leadership integrates values-based leadership into an understanding of an energetic holographic world. It is a world where the unseen is the primary influencer, where the smaller is more powerful (Bohm, 1994). I will synthesize many diverse ideas into an exploratory theory that will suggest new insights into sustainable leadership. I will propose a new model of practice from which to work. I suggest that it is through an internal state of physiological coherence and psychological balance that a leader can truly learn to “hold steady” (Heifetz, 1994), creating an intentional holding environment, a coherent group dynamic, which draws forth potentials from the unseen world. My hybrid dissertation marries theoretical suppositions with a model of practice, and is based on my own heuristic knowledge from the business world.
